It seems like Kim Kardashiancan’t get enough of showing off her post-baby body. Not only has the reality star been stepping out in one revealing outfit after another, but she also starred in Kanye West’s new music video…completely naked.

Since she spent a couple of months away from photographers after giving birth to North, many are questioning whether or not the 32-year-old was able to take the baby weight off naturally. With all that’s said about her in the media, it’s impossible for Kim to defend herself against every negative comment — but she couldn’t bite her tongue this time!

“I am very frustrated today seeing reports that I got surgery to lose my baby weight” she tweeted. “This is FALSE. I worked so hard to train myself to eat right & healthy, I work out so hard & this was such a challenge for me but I did it!!! I’m so proud of my accomplishment and NO ONE will take this away from me with fake reports! Say what u want about me but I work hard & am the most disciplined person u will ever meet.”

Currently, Kim and North are on the East Coast, supporting Kanye on his Yeezus tour.
